I am altering a jpg photo and saving it as a jpg but I can't open it because it says the file format is unrecognized?? I have been doing this for years with this software and never had aprobem before??
Occasionally I run into a similar problem. If the client has accidently changed the file extension to .jpg eventhough the file is actually a .tif file. Photoshop wont open the file until I change the file extension back to .tif and then it opens fine.
